Data Mining - (Discriminative|conditional) models

Thomas Bayes


Discriminative models, also called conditional models, are a class of models used in machine learning for modeling the dependence of an unobserved variable y on an observed variable x.

Discriminative models, as opposed to generative models, do not allow one to generate samples from the wiki/joint distribution of x and y. However, for tasks such as classification and regression that do not require the wiki/joint distribution, discriminative models can yield superior performance.
